Anthropic made Claude Opus 5 the default flagship on Jul 24 2026. Official list price is $5 input and $25 output per million tokens with a 1M-token window. On CompareLLM that row is a dated snapshot, not a claim we reran SWE-bench in-house. Use it as the Claude side of “claude vs gpt benchmark” until a later SKU outranks it on preference Elo.
What the SKU actually is
Opus 5 sits above Sonnet 5 and below Fable 5 on the invoice. Computer-use and long-horizon agents are the stated jobs. If you only need a chat widget, this is the wrong default — look at Haiku 4.5 or Gemini Flash first. If you need the current Anthropic crown versus OpenAI, open Opus 5 vs GPT-5.6 Sol.
Empirical Evaluation & Architectural Analysis
Empirical evaluations recorded across the CompareLLM Leaderboard highlight how parameter scaling and inference optimization impact production throughput and cost-per-token economics. Reference the interactive scorecard above for verified snapshots or inspect the dedicated claude-opus-5 dossier.
How we will update the cells
Daily ingest overwrites seed Elo, SWE-bench, and list price when OpenRouter, Arena, LiveBench, or official SWE-bench JSON match an alias. Until then the cell source is seed-bootstrap. Blank cells stay blank.
